I am using AppsScript to send emails by prompts on GoogleSheets. When I test the AppScript, the email appears in my Sent box; however, it does not appear in the recipients inbox.
I have tried manually sending the same email; it appears in my Sent box and does appear in the recipient's inbox. I do not understand how an email can appear in by Sent via both AppScript and Manually, yet only the manual email appears in the recipient's inbox.
